But really, should you do your own homework?

Hi...

 This code may help you and  i took n=5;

%x(t) = 0.5+2\n (cos -1\3*cos 3t +1\5 cos 5 t - 1\7 * cos 7t); t=-10:10; n=5; for i=1:length(t) x= 0.5+(2\n); x1=cos(-1\3)(cos(3*t(i))); x2=(1\5)*(cos(5*t(i))); x3=((1\7)*cos(7*t(i))); xf(i)=x*x1+x2-x3; end
